John Gilkey

The sets are gone, and the costumes, and that giant blue-and-yellow tent. Master clown and performance maker John Gilkey has ended his fourth stint with Cirque du Soleil since 1996. But if the wiry, often wild-haired Gilkey and his Muppet-like mug are no strangers to the big time,they move just as ferociously through a bare stage in a small venue wearing not much more than, these days, a bushy beard.

It’s been three years since Gilkey last performed in San Francisco — flanked by comedians Alec Jones-Trujillo and Donny Divanian, the deadpan naïfs of his avant-comedy trio, We Are Nudes. Just as the very funny yet vaguely unnerving, off-center style of Nudes occupied some indeterminate territory between sketch comedy and Dadaist destruction, Gilkey’s latest venture — the Los Angeles–based eight-member improvisational ensemble known as Wet the Hippo — takes its audience beyond the usual endpoints of improv.
